that this can be done without
erasure, the only one of them that is
simplicative, being rendered complicative. In
the next place, since the result aimed at must
be of extreme simplicity, it is necessary to place
restrictions upon the employment of the complicative
operations. To this end, each of these
was studied and the precise ways in which it
could further the general purpose of the rule
was ascertained; and thus (??) in place of the complicative
operations were substituted a set of
operations condusive to the purpose.

The process of the rule is, as I said, probably not the
most facile. But since the system of existential
graphs is not intended as a calculus
